What are the precautions when using an air filter?

2018-10-19 18:42:42

An air filter is a device that traps dust from a gas-solid two-phase flow through the action of a porous filter material and purifies the gas. It purifies the air with low dust content and sends it into the room to ensure the process requirements of the clean room and the cleanliness of the air in the general air-conditioned room.
(1) coarse filter
The filter material of the coarse filter is generally a non-woven fabric, a wire mesh, a glass filament, a nylon mesh or the like. Commonly used coarse filters include: ZJK-1 automatic winding type herringbone air filter, TJ-3 type automatic winding flat type air filter, CW type air filter, and the like. Its structural form is plate type, folding type, belt type and winding type.
(2) Medium efficiency filter
Commonly used medium efficiency filters are: M-I, II, IV foam filters, YB glass fiber filters, and the like. The filter material of the medium efficiency filter mainly includes glass fiber, medium pore polyethylene foam and synthetic fiber felt made of polyester, polypropylene, acrylic and the like.
(3) High efficiency filter
Commonly used high efficiency filters are available in GB and GWB types. The filter material is ultra-fine glass fiber filter paper with very small pores. With a very low filtration rate, this enhances the screening and diffusion of small dust particles, so it has a high filtration efficiency.
Classification and function
The compressed air coming out of the gas source contains excessive water vapor and oil droplets, as well as solid impurities such as rust, sand, pipe sealant, etc., which will damage the piston seal ring and block the small vent holes on the components. Shorten the life of components or disable them. The function of the air filter is to separate the liquid water and liquid oil droplets in the compressed air, and to filter out dust and solid impurities in the air, but not to remove the gaseous water and oil.
